Question

$T$ is lighter in weight than which of the other two iron articles?

• A. $P,Q$
• B. $S,R$
• C. $P,R$
• D. $S,Q$

Answer 1

The correct option is A $P,Q$

From the given information, we find that

$P=2Q$; $Q=\frac{9R}{2}$; $R=\frac{S}{2}$; $S=\frac{T}{2}$

Now, calculating each weight in terms of $T$, we get

$P=2Q=\frac{9T}{4}$; $Q=\frac{9R}{2}=\frac{9T}{8}$; $R=\frac{S}{2}=\frac{T}{4}$; $S=\frac{T}{2}$

If we arrange it in terms of weight (from lightest to heaviest), we get,

$R<S<T<Q<P$

Clearly, $T$ is lighter in weight than $P$ and $Q$.
